The U.S. economic environment is "very good" and the stock market's rally to multi-year highs has more room to go, said Goldman Sachs Chairman and CEO Lloyd Blankfein in a CNBC interview from the World Economic Forum in Davos, Switzerland.
"The market has gone up with people being under-invested," Blankfein told "Squawk Box," adding that investors should want the market to go down "so they can get in."
